CARPET SWEEPERQ Application filed June 2, 1925, Serial No. 34,448, and. in Great Britain February 18, 1925.

The invention relates to carpet sweepers which are fitted or provided with corner buffers or cushions of rubber or similar resilient material and a guardyband' or cord carried round the case of the sweeper to prevent damageitofurniture and the sweeper.

We find that during the use of the sweeper such cushions or buffers are liable to dis placement and the object of the invention is to provide a particular means of securing the cushion or buffer firmly in position upon the end iron.

According to the invention the cornerbuffer or cushion is made with a transverse groove or slot centrally disposed in combination with a metal clip inserted therein and affixed to the end iron or direct to the wood case.

The invention will be fully described with reference to the accompanying drawings.

The carpet sweeper is of ordinary or known construction with case A, brush B, driving wheels 6, end iron a, furniture guard C, and fitted with corner buffers or cushions D which are the subjectof this invention in combination with metal fasteners.

The corner buffers or cushions D may be either tubular with a central bore to thread over the furniture guard C or may be made with a longitudinal groove on the underside to fit over the furniture guard C but in either case each lies upon or rests against the corner of the end iron or which is preferably pressed or stamped inwards to form a slot and inwardly pressed member a with which a projection or projections d on the underside of th buffer or cushions D en-- gage.

As hitherto made and applied the bufi'ers D were very liable to displacement in use or when the furniture guard C stretched and this invention provides a firm and secure attachment which will permanently retain the buffer in position.

Each buffer is made with a transverse groove or slot 65 disposed centrally of its length and is firmly secured by a metal clip E E E E or E to the end iron a or to the case.

In the form shown in Figs. 1 to 10 the corner-buffer or cushion D is made with an external transverse groove Z centrally disposed and the metal clip E is made to completely encircle it and the corner iron a, the two ends being secured together by one end hooking into a slot in the other end as shown in Figs. 3 and 9. or the metal. clip E may be made as in Fig. 10 with inturned ends to' spring under the corner iron at.

In the form shown in Figs. 11 and 12 the corner buffer or cushion D is made with an external transverse groove (Z as in Fig. 2 and the metal clip E is made with side flanges by which when it is placed around the buffer it is aflixcd by screws 6 to the wooden sideof the sweeper case.

In the form shown in Fig. 13 the corner buffer or cushion D is made with an external transverse groove d as in Fig. 2 and the metal chp E which embraces it is made in the form of a staple and driven through the end iron a into the wooden side of the sweeper case.

In the form shown in Fig. 14; the corner buffer or cushion D is made with a transverse groove or slot (Z in the top and the metal clip E is made in the form of a staple and driven down through the sides of the butter D and through the end iron a into the wooden side of the sweeper case.

In the form shown in Fig. 15 the corner buffer or cushion D is made with a transverse slot d and the metal clip E is similar to that shown in Figs. 9, 10 or 12. It is passed through the transverse slot and secured to the end iron at or to the wooden side of the sweeper case as in Figs. 4, 5 or 11.

What I claim as my invention and desire to protect by Letters Patent is In a carpet sweeper having a case, end irons, and a furniture guard the combination of a corner hufier provided with a longitudinal central bore through which the furniture guard is passed and a transverse groove disposed centrally of its length fitted at each corner and a metal clip within the transverse groove of each buffer and extending around the adjacent end iron substantially as described.

In testimony whereof I have hereunto set my hand.
